...Albert Sabin, medical researcher, developer of oral polio vaccine . . . . . . . Sc.D...
...backed Salk vaccine as the most effective means of preventing paralytic poliomyelitis. Last week in seeming contradiction, the A.M.A. Journal printed a judgment that "much of the Salk vaccine used in the U.S. has been worthless" - a charge that could snarl plans to get millions of Americans inoculated before polio begins its 1961 northward march with advancing summer. The Scripps-Howard newspapers headlined the statement, and Congressman Kenneth Roberts of Alabama urged an investigation...
...facts are that some Salk shots have been worthless because the vaccine lost its potency with age, or because manufacturers, determined to make it safe, overdid the job of inactivating the virus. Despite this, overall effectiveness of Salk vaccine in preventing paralytic polio has ranged statistically from 75% to 90%. As Dr. Jonas E. Salk retorted: "The continued occurrence of polio is not due primarily to failure of the vaccine, but to failure to use it." But most authorities admit that for fuller protection, the U.S. needs a more potent vaccine, probably the Sabin oral type, which should be available...
...play it safe. It recommended immediate, intensified efforts to get Salk shots into young children and young adults, the two most vulnerable age groups. Dr. Sabin won a grudging endorsement: "The PHS should continue to make every effort to encourage the early production and ready availability of an oral polio vaccine." Best estimates were that it would not be ready much before next winter-too late to take effect in the peak polio months...
